5.1.3 User Density
Total User Density depends on device type.
For example, 32MB in the SLC Mode requires 64MB in MLC.
This results in decreasing of user density.

5.1.4 Auto Power Saving Mode
If host does not issue any command during a certain duration (1ms), after previously issued command is completed, the device enters "Power Saving
mode" to reduce power consumption.
At this time, commands arriving at the device while it is in power saving mode will be serviced in normal fashion

6.0 REGISTER VALUE
6.1 OCR Register
The 32-bit operation conditions register stores the VDD voltage profile of the e·MMC. In addition, this register includes a status information bit. This status
bit is set if the e·MMC power up procedure has been finished. The OCR register shall be implemented by all e·MMCs.
[Table 30] OCR Register
NOTE :
1) This bit is set to LOW if the e·MMC has not finished the power up routine
2) The voltage for internal flash memory(VDDF) should be 2.7-3.6v regardless of OCR Register value.
6.2 CID Register
[Table 31] CID Register
NOTE :
1),4),5) description are same as e.MMC JEDEC standard
2) PRV is composed of the revision count of controller and the revision count of F/W patch
3) A 32 bits unsigned binary integer. (Random Number)
